Christina Ricci paraded around naked on the set of her new film.The 'Addams Family' star, who plays nymphomaniac Rae in 'Black Snake Moan',got into character by stripping off in front of the cast and crew.Christina said: "I needed to lose any sort of self-consciousness because I feel sometimes you can see self-consciousness in a performance when somebody is naked or in a nude scene."I really needed for that not to be there, so to help me I stayed the way I would be for the scene all the time - in order to get the crew really used to seeing me that way. Not only was I comfortable, but I could look at anybody's face and see they were comfortable."It was really necessary for the crew to be used to me undressed because I was playing someone who places no value on her body. She has no regard for herself so she wouldn't care if she were clothed or not."The 27-year-old became so used to being naked she was still walking around undressed after filming finished. She said: "It was kind of funny because, you know, I'm a prude and I do not like walking around naked."I was in my bathroom about two months after the movie finished and I was brushing my teeth and I was in my underwear. I looked down and it was like,'Oh, god, put something on.'"And then I just stopped and thought, 'Oh my god, I was half naked for two months and my ass was on camera.' "
